Student Loan Consolidation

Interest Rates

The interest rate on a consolidation loan is the weighted average of the interest rates on the loans being consolidated, rounded up to the nearest 1/8 of a percent and capped at 8.25%.

For example, suppose a student has just unsubsidized Stafford Loans originated on or after July 1, 2006. These loans have a fixed interest rate of 6.8%. When they are consolidated by themselves, the consolidation loan will have an interest rate of 6 and 7/8ths of a percent, or 6.875%. So the interest rate increases only slightly.

If the borrower has a mix of loans with different interest rates, the weighted average will be somewhere in between. For example, if the borrower has $5,000 of Perkins Loans (at 5.0%) and $10,000 of unsubsidized Stafford Loans (at 6.8%), the weighted average is

     $5,000 * 5.0% + $10,000 * 6.8%     ------------------------------ = 6.2%     $5,000 + $10,000       

This weighted average, 6.2%, is then rounded up to the nearest 1/8th of a percent, yielding a consolidation loan interest rate of 6.25%.

Note that the weighted average does not fundamentally alter the underlying cost of the loan. It preserves the cost structure by including each interest rate to the extent that it applies to part of the overall loan balance. For example, the consolidation loan in the previous paragraph says that of the $15,000 consolidation loan balance, $5,000 will be at 5.0% and $10,000 at 6.8%, yielding an equivalent interest rate of 6.2%.
